Accepting multiple words with cin?
Author
I was wondering how to take more than 1 word with cin?
Like in a MUD if you type something like:
look monster
It would put look somewhere like Input[0] and monster at Input[1]
This is something I never learned to do before going to Win32 programming, and I got curious about it because of a project im working on.
I assume you''re doing
--
string input;
cin >> input;
--
If so, yeah, input is essentially a "token".
You could do...
--
string line;
getline(cin, line);
--
that will read a line''s worth of input into line.
--
string input;
cin >> input;
--

That puts the whole thing into the var, im wondering if theres something to spread each word into an array of strings or something.
Try this:
int i;
char Input[ 100 ][ 80 ];
for ( i = 0; i < 100; i++ )
{
cin << Input;<br>}<br><br>for ( int j = 0; j < i; j++ )<br>{<br> cout >> Input[ j ] >> " - ";<br>}<br><br>I''m not sure about it, but I seem to remember it from C++ class.<br>Try it.
int i;
char Input[ 100 ][ 80 ];
for ( i = 0; i < 100; i++ )
{
cin << Input;<br>}<br><br>for ( int j = 0; j < i; j++ )<br>{<br> cout >> Input[ j ] >> " - ";<br>}<br><br>I''m not sure about it, but I seem to remember it from C++ class.<br>Try it.
std::string line;std::getline( std::cin, line ); std::stringstream ss(line);std::istream_iterator<std::string> beg(ss), end;std::vector<std::string> words(beg, end);If user enters:
"look monster"
then:
words[0] == "look" && words[1] == "monster"

What about...sscanf("%s %s", input1,input2);
strcmp(input1,input2)?
Somthing like that?
That will only work if your string has two words, you have two variables, and they are preallocated char buffers. It won''t work nicely with C++ containers nor strings.
